This invention relates to improvements in shower door enclosure structures.

The main objects of this invention are to provide improved shower-enclosuredoor-frame members and mounting fixtures of a form and arrangement which will permit quick and easy assembly and installation at the point of use; to provide improved shower-door frame members and mounting fixtures of this kind which suspend the doors on rollers operating in concealed tracks and retain the doors vertically during movement by concealed guideways; and to provide improved door-frame members and mounting fixtures of this kind which are simple in construction and ornamental in appearance, making possible economic manufacture and shipment in completely knockdown or disassembled form and easy assembly and mounting by the purchasers with little or no experience, using locally-obtained door panels.

One specific embodiment of this invention is shown in the accompanying drawings, in which:

Figure l is a perspective view of a bath tub and shower equipped with a shower-enclosure structure embodying this invention.

Fig. 2 is an enlarged perspective view of the assembled shower-enclosure structure, portions thereof being broken away and omitted to more clearly indicate the internal form and arrangement of the several parts.

Fig. 3 is a fragmentary, inside perspective, partly in cross-section, of a lower part of the structure, as viewed from the plane of the line 3-3 of Fig. 2.

Fig. 4 is an enlarged, vertical cross-section of the assembled structure taken'" on the plane of the line 4-4 of Fig. 2, intermediate portions of the structure being broken away.

Fig. 5 is an exploded view of one of the door-panel frames and its fastening parts, and

Fig. 6 is a fragmentary, cross-sectional detail taken on the line 6-6 of Fig. 4.

The essential concept of this invention involves endmitered, U-shape side members and h-shaped top and bottom members for framing the requisite door panels, the off-set flanges on the upper members mounting suspension rollers concealed in a channeled top supporting fixture resting on the vertical jamb fixtures and the offset flanges on the lower members functioning as guides concealed in a channeled bottom cross fixture fitting between the ends of the jamb fixtures and anchored to the rim of a bath tub.

A shower-enclosure structure embodying the above concept includes door-panel frame members for doors D and four mounting fixtures, all separately formed with a view to having the door-frame members assembled around selected door panels and secured in appropriate operative relationship with the fixtures at the point of use. The door-panel frame comprises top and bottom members 11 and 12 and side members 13 and 14 together with angle plates 16 and their fastening screws 17. The mounting fixtures comprise a top 18, a bottom 19, and a pair of jambs 20.

The top and bottom door-panel members 11 and 12 are of substantially h-shaped in cross-section, providing channel parts 21 and outwardly disposed flanges 22 and 22 respectively. The side members 13 and 14 are of substantially identical U-shape. The exterior faces of the channel parts 21, of the top and bottom members 11 and 12, and the side members13 and 14 are here shown fluted to produce an ornamental effect. The ends of each member are mitered so as to allow them to fit.

closely together around a door panel 23. Internally, the channel part of all of these four members 11, 12, 13 and 14, intermediate the base and the open edges, are formed with ledges 24 against which the peripheral edges of the door-panel 23 abuts with an interposed U-shaped cushioning strip 26. The cushioning strip 26 is preferably of the screws 17 when inserted through apertures 29 in the respective frame members (see Fig. 5). When thus secured in place, as a frame around the panel 23, the opposite legs of these angle plates 16 are held against the inside bases of the channels of the respective doorframe members 11, 12, 13 and 14 outwardly of the perimeter of the door panel 23, as will be most evidentfrom Fig. 5.

Each door D, when assembled, has a handle 30 (see.

Figs. 4 and 6), the flange of which is anchored between the face of the door panel 23 and the outer leg of the U-shaped side member 13 or 14.

The fixtures 18, 19 and 20 all are of differing construction in order to provide an appropriate mounting for the sliding doors D.

The top fixture 18 is U- or channel shape with opposed,

transverse ledges 31, which are recessed on their innermost faces to form runways or tracks 32for the door suspension rollers 27. It will now be seen (Fig. 4) that the doors are spaced from each other as shown by the numeral 33. flanges 34 are spaced to enhance the beauty of design, and the distal or free ends thereof fit snugly over the top ends of the jamb fixtures 20 to afford the sole support for the top fixture 18 and its suspended doors D.

. The bottom fixture 19, formed for positioning on the outside rim of the tub T, as shown in Fig. 1, is of double E cross section (see Fig. 4) with the dividing web 41 inclined to the opposite faces of the fixture. The upper portion of the fixture 19 provides guideways 36, on opposite sides of a medial flange 37, for the flanges 22' on the bottom door frame members 12. The ridges 38 on the under side of the bottom fixture 19 provide for the application of mastic for bonding the fixture to the tub T. This fixture is set on the tub with its distal ends seated in the lower end of the side jambs 20. Drain apertures 35 are formed along the medial flange 37 and the inner ridge of the fixture 19 to insure draining of the water into the tub T as it runs down off the doors D.

The form of the side or jamb fixtures 20 is best shown in Figs. 2 and 6. Along the base of the channel is secured resilient cushioning strips 39 of rubber or some comparable pliable material to afford a watertight, slightlyyielding abutment for the doors D. Like the bottom fixture 19, the ridges or rails 40 on the jamb furtures 20 allow for the application of mastic to secure a watertight seal between the jambs and the walls to which they will be otherwise anchored.

The former mounts the suspension rollers 27 (see- Below the track flanges 31, the lateral This shower-enclosure structure is assembled and mounted on and around the tub T in the following manner:

The door-frame members 11, 12, 13 and 14 are first assembled around door panels 23 of suitable material, glass or some plastic such as presently in so much use for that purpose. These several frame members and the angle plates 16 and screws 17 are laid out as shown in Fig. '5. The U-shaped cushion strip 26 is placed around the perimeter of a panel 23. The angle plates 16 are attached to the opposite ends of the side members 13 and 14 by means of screws 17 inserted through apertures 29. Then, one after another, the frame members 11, 12, '13 and 14 are placed over the cushion-stripped door panel perimeter and secured in place by inserting the screws 17 through the apertures 29 in the top and bottom members 11 and 12 to engage the threaded apertures 28 in the other legs of the angle plates 16.

The jamb fixture-s 20 are placed in position first. They are first temporarily set up against the respective walls and made sure that they are plumb in both directions, whereupon the points for the anchoring screws are spotted. After subsequently applying mastic to the middle ridge 40 of eachjamb '20, they are set in place and anchored to the walls by appropriate screws.

The bottom fixture is cut to fit snugly between the jambs 20 on the top of the tub T, as most clearly shown in Fig. 1. Before applying mastic to the middle ridge or rail '38 the fixture is tested for its level on the tub, the same being shimmed up where necessary to make it level. the fixture 19 set in place as shown in Fig. 1.

The top fixture 18 is cut to a length to fit readily between the walls, to which the jambs 20 are anchored, and so that it will rest on the ends of those jambs. Before final placing of the fixture 18, the doors D, with their rollers 27 upward and the flanges 22 back to back, are run in on the respective track ledges 31. This assembly of the doors D on the top fixture 18 is lifted up and positioned so that the flanges 34 slip down over the top ends of the jambs 20 with the flanges 22' of the bottom door frame members 12 disposed in the guideways 36 in the bottom fixture 19, as shown in Figs. 2, 3, and 4. The top fixture 18, when thus seated on the jarnb fixtures 20, is automatically locked in place and the enclosure is ready for use.

Although but one specific embodiment of this invention is herein shown and described, it will be understood that numerous details of the construction shown may 'be altered or omitted without departing from the spirit of the invention as defined by the following claims.
